摘要
描述了一种新的截面三维重建方法,它是在截面重建法的基础上,引入仿射变换作为旋转、投影变换,利用线性插值消隐填充算法,生成物体的可视侧面,直接利用重建图象的深度信息计算可视侧面的灰度,在显示平面获得物体可视侧面的三维结构及形状信息.并可通过旋转投影变换获得物体任一可视侧面的重建显示图象.
On the basis of the section reconstruction method, by the introducing of the affine transform used as rotation and projection transform, and with the help of the linear interpolation elimination fill algorithm for the generation of the visible surface of an object, a new method for 3-D section reconstruction from scries slices images is presented. The 3-D structure and shape of an object arc displayed with the help of the grey of its visible surface calculated from the depth-distant message of the reconstructive image, and the reconstructive image of any visible surfaces of an object can be obtained by the rotation and projection transform.
